For each property listed, identify the type of element it describes.
very good electrical conductivity:
amphoteric, able to form acidic or basic compounds:
gaseous at room temperature:
solid at room temperature:
brittle:

1.Very good electrical conductivity : Metals (Decreacing order of conductivity)

2. Amphoteric : Metal elements

3.Gaseous at room temperature: mostly Nobel gases elements and some non - metal elements.

4.Solid at room temperature: Mostly Metals (few non-metals, metalloid elements)

Non- metals(Carbon ,Boron )

Metalloids(antimony)

5. Brittle : non - metals (can't be rolled into wires)

Hydrogen , carbon , sulfur , phosphorus
